The report “ California’s Education Skills Gap: Modest Improvements Could Yield Big Gains” ( Public Policy Institute of California, April 16, 2008, www.ppic.org) states that nation-wide, 61% of high school graduates go on to attend a two- year or four- year college the year after graduation. The proportion of high school graduates in California who go on to college was estimated to be 0.55. Suppose that this estimate was based on a random sample of 1,500 California high school graduates. Is it reasonable to conclude that the proportion of California high school graduates who attend college the year after graduation is different from the national figure?
